[PATCH v2 00/14] etnaviv: add OES_texture_half_float support

[Christian Gmeiner]

This patch series adds support for half-float textures. This version
of the patch series got a little bit bigger as it adds support for
'multi layer' formats for the RS and seperates RS and PE format tables.

Patches 1-7 are adding support for a seperate entry for PE format and
'multi layer' format support for RS.

Patches 8-13 are adding basic support float formats in mesa and etnaviv.

Patch 13 adds float formats and enables OES_texture_half_float.

It passes piglit/bin/oes_texture_float half and fixes some other piglits
on the way.

Christian Gmeiner (14):
  etnaviv: add own format entry for pe formats
  etnaviv: fix some rs format mappings
  etnaviv: rs: add support for multi layer formats

  mesa: handle OES_texture_half_float formats in _mesa_base_tex_format()
  etnaviv: HALTI0 indicates extended pe formats
  etnaviv: update RS_FORMAT_MASK to include extended formats
  etnaviv: add support for extended pe formats
  etnaviv: handle 8 byte block in tiling
